We'll see what that outcome of all that will be. Some poeple in the GAF thread mentioned something along the lines that in the licensing agreement of steam the right to use the copy is NOT unlimited like it is in the wording of this ruling. Although if this would be true, there's a chance that the EU court would rule that the license agreement of steam is invalid. On the other hand, I'm also not sure if this means that Valve (or any other distributor) has to actually develop a way that you can actually sell a game, because right to there is no way to detach a game license from an account, as the case of Oracle was about keys as I understand it.
In germany our highest court two years ago that explictly granted Valve the right to deny selling of licenses on steam, but this decision by the EU court would overrule that. But still, I believe when I see it. We have the right by law to make up to 7 physical copies of any medium, game, music, dvd etc. (and even are allowed to share the copies with friends) but are explicitly not allowed to crack a copy protection which obviously means that the right to make a copy is absolutly useless, at least in regard to games.
